A limited number of Android fans have already begun testing the beta version of Android Q but expect to hear more from the US technology firm about an official release and confirmed features.

Some of the things we already know about Q is that it will feature improved privacy tools and there will be in-built support for foldable phones.

Perhaps one of the most exciting new additions is something called "bubbles".

The concept behind this new feature is that it will present certain app functions, such as text messages, within a small circular icon that can be moved around the user's display and opened at will.

The functionality works similar to that of Facebook Messenger's Chat Heads.

Google has insisted bubbles will "help users prioritise information and take action deep within another app, while maintaining their current context".

Speaking about the feature, Google said: "Bubbles are great for messaging because they let users keep important conversations within easy reach. They also provide a convenient view over ongoing tasks and updates, like phone calls or arrival times.

"They can provide quick access to portable UI like notes or translations, and can be visual reminders of tasks too."

A number of other notable features in Android Q include a more efficient share sheet, simpler Wi-Fi connectivity and the possibility of a system-wide dark mode.

NEW HARDWARE

Today's announcement might not just be about software as numerous rumours have suggested that Google will also reveal new hardware at today's event.

The main news could be the launch of two new Pixel phones called the 3a and 3a XL which may arrive with decent specs at a much lower price.

In fact, it's thought both phones will get Google's brilliant Pixel 3 rear camera which currently offers one of the best experiences on the market.

Although not confirmed it's likely that fans will be able to tuck the 5.6-inch 3a in their pocket for under £400 and the larger 6-inch XL may cost under £500.

We'll find out full details later but this could be good news for those wanting to own a Pixel device on a smaller budget.
